Ahh... Giovanni's small yet important role in Mewtwo Strikes Back. He's left out of a lot of the basic stuff... but not in the book or the comic book! And I have obtained copies of both! For your viewing pleasure!
Disclaimer- The book Pokemon the first movie: Mewtwo Strikes Back is a movie adaption by Tracey West. Not me. She wrote all the little details like thought and such and did a good job. I didn't write this. And it belongs to Nintendo and others. The comic book was Pokemon the First Movie: MewTwo Strikes Back issue 1. Once again, I didn't write it. Lotsa People worked together to do it. The stroy actually was written by Takeshi Shudo and Hideki Sonoda. Not me. Don't sue.
